LED Characteristics Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12339

The LED Characteristics Apparatus is a physics and electronics laboratory instrument used for studying the voltage-current characteristics of a light emitting diode. It is suitable for schools, colleges, STEM labs, and electronics practical sessions where students need to observe forward bias behaviour, threshold voltage, and diode conduction experimentally.

Product Description

The School Equipments LED Characteristics Apparatus helps students plot the V-I characteristic curve of an LED under controlled laboratory conditions. It is used to demonstrate how an LED behaves as a semiconductor diode and how current changes after the forward voltage reaches the conduction region.

This apparatus is valuable for physics and electronics teaching because it converts semiconductor theory into a measurable practical experiment. Students can vary voltage, observe current, record readings, and understand the relationship between applied potential difference and light emission. The exact voltage range, current range, meter type, LED colour, power supply details, and accessories should be confirmed before publishing or procurement.

How to Use the LED Characteristics Apparatus

1. Place the apparatus on a clean, dry, and stable laboratory table.
2. Check the LED section, terminals, meters, and power input before switching on.
3. Connect the circuit as per the supplied experiment guide.
4. Apply a low initial voltage and increase it gradually within the confirmed range.
5. Record the corresponding current reading for each voltage value.
6. Observe the point where the LED begins to conduct and emit light.
